Hi all. I’m new heee and this is my first post. I’m working on changing coils on my sons 2005. After everything was reinstalled and putting the battery back in I noticed two wires coming from the battery cable harness that were broken off. It was a single yellow/black small gauge wire and a little bigger gauge single grey wire each in their own plastic sleeve. Does anyone know where these go. I included a pic of them removed from the wire cover. Thanks for the help in advance

 

They don't look like factory wires to me, so ask your son what those are for.

 

Suggestion,,,,,,,,,,,,,if you have a test light or voltmeter to use,, Check and see if and when those wires are connected to any power source,key on for example.

If never powered , no cause for concern, but if powered at anytime , that would provide some idea of where they go or come from.,

Black and Yellow colored wires many times are power source wires.
